2 T E E !H 2% m N w +U m a D1 side plates 11 of the mold is formed themold cavity, in which the concrete material 150 is placed. The lowerinside plates 11 are so adjusted by means of the bolts 9, that theirflanges 120 rest a distance above the floor 2, equal to the thickness itis desired to give to the bottom of the concrete vault or receptacle,the whole inside being sup ported by the cross beams 13, as abovedescribed. When the concrete is poured in through the open top 15 of themold, it is allowed to rise until it reaches these flanges 120, when theconcrete is then poured into .the mold cavity between the inner andouter plates, until it reaches nearly to the top of said cavity.- By thetime the mold cavity is thus formed, the bottom may be struck oil, orleveled, using the flanges 120 as guides to "determine the finalthickness of said bottom. After this is donepthe concrete will besufliciently solid to support the side plates 11- and to permit theremoval of the supporting beams 13.

The rabbet forming strips :17 may now be placed in the mold cavity, andthe concrete filled up-to the top of the latter and smoothed off; orthese strips may be placed in said cavity at any earlier stage andsuit-ably supported from the outside.- When the strips 17 are removed arabbet 151 Will be formed in the finished receptacle 150, as shown inFig. 6, which latter is obtained by disassembling the parts of the moldafter the con; crete has sufiiciently hardened.

The operation of the form or mold will be clear from the above, butitmay be summed, up as follows :VVhen it is desired to assemble themold, the floor- 2, it a floor is to be used, is first brought intoposition; the outer and inner plates are so adjusted the one over theother as to form a mold cavity having any desired inside ancl outsidedimensions and said plates are firmly secured togetherby means of thebolts 9; the

longitudinal upper and lower outside supporting bars are brought intoposlt-ion, and the outside end bars are secured thereto by 'means of thebolts 302 passing through the proper holes in said bars. The uprights1-.

are secured over said outside bars after the ns de plates have beenbrought into position inside said outside plates. The inside strips 18and21 and the adjustable Spreaders l!) and 20 are brought into place,and the whole inside wall of the mold cavity suspended. by the crossbars 13, as above described.

The flanges 12,120 and 130 are important-- features of this invention,for they serveto; stiifen the plates as above stated, and thereby permitthem to be made so light that.

they can for ordinary burial vaults be handled by one man by hand. Andthe flanges 120, are an additional especially important feature of thisinvention, for not only do they secure the necessary strength abovedescribed, but they support the plates on the concrete while it sets,and constitute a convenient and ready gage by which the workman may atonce know'the thickness of the bottom of the vault and may level it offwithout any delay Whatever.

After the vault is formed in the manner above set forth, the form ormold 60, shown in Fig. 5, may be used to form the. finished cover 70,shown in Fig. 7, which is preferably provided with the handles 71 beforethe concrete sets.

Various changes coming within the spirit of this invention will readilysuggest themselves to those skilled in the art, and therefore I do notwish to be limited to the exact details of construction, except asspecified in the claims.

What I claim is V 1. Ina form or mold for concrete receptacles, thecombination oftelescoping inner and outer side and end walls flanged attheir In a foian or mold for concrete recep- 'tacles, the combination oftelescoping inner and outer side and end walls flanged at their topedges and provided with registering holes, and bolts adapted to securesaid sides together; telescoping upper and lower outer side andendsupporting bars, also provided with registering holes; two pairs ofhorizontal supporting strips 18 and onepair of vertical strips 2-1adapted to rest on the inside of said inner Walls; and adjustablespreader bars 19 and 20 adapted to extend between said strips,substantially as described.

3, In a form or mold for concrete recep' tacles, the combination ofperforated inner. and outer adjustable telescoping plates pro: videdwith stitlcning flanges at the upper edges; means comprising bolts forholding said plates in their adjusted positions; cross bars 13 extendingacross and resting on the upper-flanges of said outer plates; and boltspassing through said bars and.the flanges of said inner plates andserving to support the "same above the bottoms of said outer plates,

flanges; means passing through said beams adapted to hold the bottom,flanges of said inner plates a predetermined distance above the bottomedges of the outer plates; andadjustable- Spreaders inside said innerplates substantially as described.

5. In a form or mold for concrete receptacles, the combination of inneradjustable telescoping plates provided with registering holes andflanges on their top and bottom edges; outer plates also provided withregistering holes and flanges on their top edges; cross beams adapted torest on said latter flanges; means passing throu 'h said beams adaptedto hold the bottom ianges of said inner plates a predetermined distanceabove the bottom edges of the'outer plates; horizontal strips 18, andvertical strips 21 adapted to contact with said inner plates; andadjustable spreaders inside said inner plates adapted to contact withsaid strips, substantially as described.

(3. In a form or mold for concrete receptacles, the combination of innerand outer adjustable telescoping plates provided with stiffening flangesat their upper edges, and

said inner plates provided. with stiffening flanges at their loweredges; a bottom for said mold; cross beams 13 adapted to rest on theupper flanges of said outer plates and provided with means whereby thelower flanges of said inner plates are supported a predetermineddistance above said bottom;

and inner and outer means for holding said plates in position,substantially as described.

7. In a form or mold for concrete receptacles, the combination of innerand outer adjustable telescopin plates provided with registering holes,stit fening flanges at.- their uppenedges and-said inner plates providedwith stiffening flanges at their lower edges;

a bottom for said mold; cross beams 13 provided with recesses fittingand adapted'to,

bars on the outside of said mold and spreader bars on the inside of thesame, substantially as described.

8. In a form or mold for concrete receptacles, the combination of innerplatesfianged at their bottom edges; outer adjustable telescoping platesflanged at their upper edges and provided with registering holes; boltspassing through said holes adapted to hold said plates in their adjustedpositions; outer, upper and lower supporting side and end bars alsoprovided with registering holes; a bottom for said mold; vertical bracesst through which said supporting side plates pass; an adjustable rodpassing through said vertical braces; cross bars provided with reeessesfitting the flanges of said outer plates and provided with means forholding the flanges of said inner plates a predetermined distance abovesaid bottom; two pairs of horizontal strips 18 fitting the inside ofsaid inner plates; and vertical. strips 21, also. fitting the inside ofsaid inner plates; and adjustable Spreaders contacting with said strips,substantially as described.

In testimony whereof, I aflix my signature. in presence of twowitnesses.
